CAR-COUPLING.

SPECIFICATION forming. part of Letters Patent No. 411,460, dated September 24, 1889. 2 Application filed May l, 1889. Serial No. 309,164. (No model.)

To all whom it may concern,.-

Be it known that I, PATRICK T. MADIGAN,. of the city of Troy, county of Rensselaer, State of New York, have invented new and useful Improvements in Oar-Couplers, of which the following is a specification.

My invention relates to improvements in car-couplers; and it has for its object their construction in such a manner as will allow of their being operated to connect and disconnect from the side of the car and without exposing to danger the person making the connection or disconnection, and the further object of simplifying the construction of this class of devices.

Accompanying this specification to forni a part of it there is a sheet of drawings containing three figures illustrating my invention, with the saine designation of parts by letterreference used in all of them.

Of these illustrations, Figure l shows a perspective of a part of one end of a car with my invention applied thereto, which in construetion and arrangement is the same at each end of the car. Fig. 2 is a top view of the same parts, showing apart of the buffer-platform and the buffers. Fig. 3 is a central Vertical section taken through the draw-head, the buffer-platform, part of the car end, and the shaft which operates the connectingpin.

The several parts of the mechanism thus illustrated are designated by letter-reference, and the function of the parts is described as follows:

The letter Edesignates the end of the car; t-he letters S its sides; B, the buffer cross-bar or platform; B2, the buifers7 and D the drawhead.

Letter L designates the coupler-link, which is preferably made at each of its ends to project beyond the eye E2 and to be narrower thereat in its cross-measurement than where inclosing the eye, and the function of this narrower part e', when used at each endof the link, is to guide the entrance of the latter into the draw-head and to keep it in a horizontal position when being entered for connection, although, if desired, the ordinary form of link may be used.

The letter T designates a slot formed in the top of the draw-head, and O an opening in the bottom thereof for the downward passage of the connecting-pin.

The letter b2 designates bearings formed in the opposite sides of the draw-head, said bearings being in the form of slots that are inclined downward as extended rearwardly.

The letterP designates the pivoted connecting-pin, whichat its front end p is extended downwardly at right angles to its shank part p2.

The letter J designates trunnion-forin journals adapted to be entered in the bearings h2, formed in the sides of the draw-head. Back .of the journals the shank part is jogged downwardly to produce the tail-piece p2', which is extended rearwardly from Wherej ogged downwardly to underlap the top of the draw-head thereat. The function of this tail-piece is to hold up the front end of the connecting-pin when it is turned down in position, as shown in Fig.

The letter E3 designates an eye formed in the top of the pin-shank, and C a chain connected with the latter thereat.

The letter S4 designates a shaft having a crank K on its outer end, and K2 acrank arranged on its inner end, to which the upper end of the chain C attaches. This shaft S4 has bearings in the straps s3 s2, attached to the end of the car, in which to turn. With the parts thus arranged when the outer crank K is turned the inner crank K2 operates the chain C to raise from out of the draw-head on its pivoted connection the downcast end p of the pin P to uncouple the link.

Vhen it is desired to connect the cars, the approaching car carrying the link L from the construction of the latter guides it into the draw-head, the pin P having at its end p been raised for its entrance by means of the cranks and the connection made between the latter and the shank of the pin by the chain O. After the link has entered, then the cranks are operated to drop the pin into place and the connection is.V made.

Having thus described my invention, what I claim, an d desire to secure by Letters Patent, 1s-

l. The combination, with the draw-head D, made with the slot T in its upper surface,the opening O in its bottom, and having` the down- IOO Wardly and rearwardly slanting bearings b2, of the connecting-pin P, made with the downcast end p', its shank or body part p2, tailpiece p3, and having the trunnion-forrn journais J at each side thereof, and I[he chain C, connecting the shank of said pin with the crank K2, arranged on the'shaft'V S4, having onf its outer end the crank K constructed and arranged to operate substantially in themanMV l 9th day of March, 1889, and in the presence of the two Witnesses Whose names are hereto ner as and for the purpose set forth.

2. The combination, With the draw-head D, made with the top slot T,the opening O, made in its bottom, and having the slotted a-nd'rearwardly-slanting bearings b2 in itssi'des, of the i connecting-pin P, made with the downcast l outer end' 19, the shank or body' part pt'he .f

ltail-piece p3, andhaving the trunnion-forin journals J at each side thereof, the chain C,

connecting with the shank of said pin, the

vshaft S4, having thereon the cranks K and K2,

with the -latter connecting with the outer end ner as and for the purposes set forth.
